Welcome to my project, an extension of my previous project Solar Power. If you haven't viewed it already, I will explain what I did. I connected three 1.5 V 240 mA solar cell together to a LED successfully. (Below)
Original setup of "Solar Cell" project.
This project got me thinking. If I left my project on the windowsill and left to do something else, the harvested power would be put to waste. I looked around for some rechargeable LED's and put the circuit together and got this:
Before using just the circuit I tried using the three batteries themselves, and, well, blew up the LED. I used ten times the current of the solar cells, which have 240 mA.
Any idea about what should I do, and is this circuit possible? Thank you for your help!
